摘要

从减少基坑开挖过程中坞墙位移和控制坞壁渗水角度出发，利用数值模拟分析，探讨在深基坑开挖中得到广泛应用的普通土钉墙和用于船坞坞室基坑开挖中的复合土钉墙技术，将联合劲性水泥土搅拌桩的复合土钉墙用于干船坞的坞墙结构。从工程探讨角度，研究土钉联合劲性水泥土搅拌桩、预应力锚杆的复合土钉墙在干船坞这一特定条件下的应用问题，并通过分析模拟结果，为干船坞坞墙设计施工过程中安全问题提出一些注意点

Abstract

From the perspectives of reducing displacements of dry dock walls during the process of pit excavation

and controlling the seepage of dock walls in the course of using

the application of techniques of soil nailing wall and composite soil nailing wall widely used in deep excavation

the construction of dry dock by using numerical simulation are explored emphatically. FLAC is one of methods of numerical simulation

which is widelyused in rock-soil engineering field. The FLAC is used to simulate the working condition of soil nailing wall in pit excavation of dock chamber; and the application of stiffened cement soil mixing pile(SMW) prestressed anchor plus soil nail structure to dock walls is studied. According to the simulation results

some sconclusions at the construction of dry dock walls are drawn.
